Abstract:Active engine mounts (AEMs) are key elements for improving automotive noise, vibration and harshness (NVH) performance. An accurate AEM model is crucial for its active control. This work focuses on the establishment and verification of a linear model for AEM with an oscillating coil actuator (OCA). Experiments and simulations of an actuator with an attached decoupling membrane and a conventional hydraulic engine mount (HEM) are employed to verify the fundamental linear models for an OCA and HEM. An integrated linear model for an AEM with an OCA is established and verified by experimental analysis of active characteristics. Based on the AEM linear model, three control algorithms, i.e., PID, Fuzzy PID and FxLMS, are established to implement an active isolation performance simulation. The FxLMS is superior to the other two algorithms for an AEM considering the active performance for rotary machine.
